BINDING-STRIP FOR LANT'ERN-SLIDES.

SPECIFICATION forming part of Letters Patent No. 668,615, dated February 19, 1901.

Application filed February 15, 1900. Renewed January 26, 1901. Serial No. 44,834. (No model.)

To all whom it may concern.-

Be it known that I, EDWARD N. BENHAM, a'

citizen of the United States, and a resident of Montclai r, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Binding-Strips for Lantern-Slides and the Like, of which the following is a specification.

My invention relates to binding-strips for use in binding lantern-slides or passe-partout frames.

Heretofore in preparing lantern-slides and the like it has been necessary to cut and fit the strips used for binding the edges of the plate; but by the use of my invention the length necessary for each edge is torn off from a prepared strip and is of such a shape that it is at once ready to be placed in position.

In the drawings forming part of this specification ,Figure l is an elevation showing a portion of a strip prepared in accordance with my invention. Fig. 2 is a cross-section taken on the line X X of Fig. 1. Fig. 3 shows a portion of the slide with the binding edges in place. Fig. 4 shows a plan view of a modification. Fig. 5 is a cross-section thereof when folded. Fig. 6 is view showing a portion of a passepartout with the binding-strips in place.

The strip A is formed of any flexible fabric, such as paper, or any material suitable for the purpose. In the form shown in the first three figures of the drawings this strip is creased atthe center and folded, as shown in Fig. 2. Its edges are notched, as shown at B, these notches being triangular in shape and spaced apart at distances equal to the length of the piece necessary for each edge of the plates. These notches are cut so nearly through the width of the strip that a section can be torn off without disfiguring its shape. I prefer to have the inner surface of the paper coated with suitable gum.

In use the plates of glass for a slide being brought together a strip is torn off, the gum moistened, and the strip applied to one edge of the plates, the notches being cut so that the length of these strips is equal to the length of the edges of the plates. Other strips of the proper length are torn 0E and applied to their proper edges, the strip for each edge being applied separately, the application of the strips being illustrated in Fig. 3.

In the construction shown in Figs. 4 to 6 I have illustrated my invention as it is used for thick plates or passe-partout frames, the only difierence of construction being that instead ofone crease there are two creases C at or near the center, so that when the strip is fold ed the center portion will be fiat, thus fitting the edge of the plate, as shown in Fig. 6. The notches are cut at such an angle that they make the proper bevel for fitting the strips over each other at the corners. Any desired angle of bevel may be used. Portions of the strips may overlap, as shown in Fig. 3, or, as will be readily seen, the notches could be cut so as to form a miter-joint between two sections of the binding.

By the use of my invention I avoid the necessity of cutting and fitting the strips to the edges of the plate when the slides are prepared.

I propose to make up these binding-pieces in any desired length, each length containing a sufficient.- number of parts for a given number of slides, or they may be made in a continuous strip and wound upona spool or reel.

I claim- 1. A binding-strip for lantern-slides consisting of a strip of flexible fabric having triangular notches at its edges at distances apart equal to the lengths required, said notches extending from the edges nearly to the center, substantially as described.

2. A binding-strip for lantern-slides consisting of a strip of flexible fabric creased at the center and having triangular notches at its edges at distances apart equal to the lengths required, substantially as described.

3. A binding-strip for photographic purposes consisting of a strip of flexible fabric having a double crease at its center, and having triangular notches .in its edges at distances apart equal to the. lengths required,

substantially as described.

Signed at New York, in the county of New York and State of New York, this 8th day of February, 1900.
